I entered the 100 yard club with my FX Impact MKII in .22 caliber. I recently decided to change to JSB Jumbo heavies after watching how well they did for the Air Hunter out of their new FX Dreamlines. They were running theirs at about 860 fps but my rifle is tuned hot and I'm sending mine out at 965 fps. In the video you will see they are flying pretty true. My rifle was shooting way high as you will see in the video and this is not the first time. I have the FX No limit mounts and I think they can be prone to move. I'm at a new section of a dairy farm that has a wealth of birds to shoot at and it is even better in the winter. This was a pigeon that presented itself as I was packing up to leave. Bill
